编辑:可以通过使用内置 jvm 参数创建可执行 jar 来避免上述所有问题。创建后,我可以使用 appbundle 将它捆绑到一个 .app 中。如何将 VM 参数集成到我的可执行 .jar 中?


我有一个可执行的 jar,我必须使用Oracle 的appbundler将其捆绑到一个 .app 中(以使其在 OS X 上运行)。如果我从终端使用java -XstartOnFirstThread -jar PhotoSelector.jar. 由于 SWT(打包在我的可执行 jar 中)和 Cocoa 限制,我必须设置-XstartOnFirstThread为 java 参数。问题是我不知道如何正确配置 Eclipse(Ant!)以将双击设置为 .app 将使用-XstartOnFirstThread参数执行我的应用程序。这些是我的 XML 文件:

构建.xml

        </java>
    </target>
</project>

构建Mac.xml

<?eclipse.ant.import?>
<project name="PhotoSelectorBundler">
<taskdef 
name="bundleapp" 
classname="com.oracle.appbundler.AppBundlerTask" 
classpath="lib/appbundler-1.0.jar" />

<target name="bundle">
<bundleapp 
    outputdirectory="dist" 
    name="PhotoSelector" 
    displayname="Photo Selector" 
    identifier="com.selector.Main"
    mainclassname="Main"
    icon="src/com/selector/256.icns">
    <classpath file="dist/PhotoSelector.jar" />
</bundleapp>
</target>
</project>

所以,我的问题是:

  1. 双击时如何默认将-XstartOnFirstThread传递给.app?
  2. 我必须在 eclipse ant 工具中选择哪些目标才能正确导出我的 .app?

现在我的 .app 已创建,但它立即关闭。我使用 appbundler 因为 Jar Bundler 不支持 Java 1.7(在我的项目中广泛使用)。谢谢!

<bundleapp>在标签中添加以下内容:

<option value="-XstartOnFirstThread"/>

我必须在 eclipse ant 工具中选择哪些目标才能正确导出我的 .app?

我不确定你在这里问什么。想必这就是你的bundleapp目标。请参阅Jar Bundler 文档以获取分步指南。

Note that a Mac app is a directory with the extension ".app". Inside of that directory you will find Contents/Info.plist file. This will contains your JVM args and other Java related info. If you continue to have problems this may be a good place to start investigating (and it would help others to answer your question as well).
